CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 406,203, dated July 2, 1889.

Application filed January 7, 1889.

To all whom it may concern:

Be it known that I, PATRICK J. EGAN, of Carleton, in the county of St. John, Province of New Brunswick, and Dominion of Canada, have invented a new and ImprovetLOaa-Ooupling, of which the following is a full, clear, and exact description.

The object of the invention is to provide a new and improved car-coupling which is simple and durable in construction, very effective in operation, and adapted to couple two draw heads of different heights.

The invention consists of certain parts and details and combination of the same, as will be fully described hereinafter, and then pointed out in the claim.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 is a sectional side elevation of the improvement as applied. Fig. 2 is a front elevation of the same. Fig. 3 is a perspective view of the coupling-link, and Fig. at is an enlarged sectional side elevation of part of the coupling-link, pin-support, and coupling-pin.

The draw-head A is provided with the usual front opening B, into which is adapted to pass the end of a coupling-link 0, adapted to be engaged by the coupling-pin D, held to slide vertically in suitable bearings in the drawhead A and passing through the opening B. The coupling-pin D is held in an uppermost position by an elastic block E, securedin the draw-head A directly behind pin D, and provided on its lower end with a shoulder F, which extends into the opening B and under the lower end of the coupling-pin D, as is plainly shown to the left. of Fig. 1 and in Fig. 4. The block E is preferably made of rubber in the shape illustrated in Fig. 4E.

The coupling-link O is provided with a bridge G, made in the form of a spectacleframe, as is plainly shown in Fig. 3. In the middle of the bridge G is secured one end of a rope H, which extends upward and passes through a suitable opening in the top of the draw-head A. The rope H is secured at its upper end to a shaft 1, extending transversely on the front of the car and mounted to rotate in suitable bearings on the same. On each block E, as shown 'to the left in Fig. 1.

$erial No. 295,616. (No model.)

outer end of the shaft I is secured a crankarm J, for turning the said shaft I so as to wind the rope H on the shaft or unwind it from the same.

The operation is as follows: When the operator desires to couple two cars, he places the link 0 in one draw-head and moves the pin D into its lowermost position, as shown in Fig. 1. This is done by pressing the shoulderF of the elastic block E rearward, after which the pin D drops into place. The operator then moves the coupling-pin of the other draw-head into its uppermost position, so as to rest on the shoulder F of the elastic The coupling-link C is then raised or lowered by turning the crank-arms J so that the rope H is wound upon the shaft I or unwound from the same, whereby the link 0 is raised or lowered to pass into the opening of the other draw-head. hen the two draw-heads come together, the projecting end of the link presses against the shoulder F of the elastic block E, so that the shoulder F is moved rearward, and the coupling-pin D is permitted to drop down, thereby locking the link in place on the other draw-head. Thus it will be seen that the coupling is effected automatically without a brakeman stepping between the cars. further be seen that draw-heads of different heights-such as are found on empty and loaded carscouple the same as draw-heads placed in a horizontal line, as the couplinglink can be conveniently raised or lowered to engage the opposite draw-head.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

In a car-coupling, the combination, with a draw-head provided with a pin-opening and a coupling-pin working therein, of the block E, of elastic material, rigidly. secured in the draw-head in rear of and adjacent to the pinopening, and provided with ashoulder, which when the block is in its normal position is in alignment with the said pin-opening, substantially as described.
